Furnace Repair & Heating Service in Larchmont
LC Heating & Air provides furnace repair in Larchmont — including heating repair, maintenance heating, home heater repair, furnace service. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.

Larchmont Village sits at the heart of the Hancock Park neighborhood, centered around the charming commercial strip on Larchmont Boulevard. The residential streets surrounding the village are lined with well-maintained period homes—Craftsman bungalows, Spanish Colonial Revival, and Tudor Revival—most built between 1920 and 1940. LC Heating & Air is based on nearby Fairfax Avenue and has served Larchmont homeowners for years. The neighborhood's older construction means most homes were built without central air conditioning and have had HVAC systems added in subsequent decades. These retrofitted systems need more careful assessment than HVAC in newer construction because the ductwork, electrical, and equipment must work within the constraints of existing architecture.
When a furnace fails, you need a contractor who understands these constraints. We don't just swap parts; we look at the whole system. Whether you are in the Rossmore Avenue Corridor or near Third Street, we provide the same-day diagnosis and honest repair advice you need to keep your home comfortable without unnecessary costs.

Larchmont HVAC Challenges
Larchmont's older homes share the challenges common to all pre-war Los Angeles construction: original ductwork that may be undersized, and electrical panels that may need upgrading to support modern HVAC equipment. We assess all of these factors before recommending any repair or replacement, ensuring that the work we do actually improves your system's performance.
Because many of these homes have systems that were retrofitted into tight spaces, access is often a major factor. We check equipment placement, line routing, and airflow before we start any work. This ensures that when we fix a furnace, it isn't just running—it's running efficiently within the specific constraints of your home's layout.
Maintaining Your Home's Character
The Larchmont area's residential character and walkability have maintained strong property values, and homeowners here tend to invest in quality HVAC systems that will last. We recommend higher-efficiency equipment only where the ductwork and insulation can support it.
We always provide honest analysis of when a premium system will actually pay for itself through energy savings versus when a standard-efficiency system is the smarter investment for the home's specific characteristics. We respect the architecture of your home and provide solutions that maintain its integrity.
Our Diagnostic Process
Every service call begins with a safety check. We verify the flue is clear and draft is adequate, test the heat exchanger for cracks using CO measurement, confirm the rollout switch is functioning, and check gas pressure at the manifold. We won't leave a system running that has a safety concern.
After the safety check, we trace the fault—whether it's an ignitor, flame sensor, pressure switch, gas valve, or control board. We explain exactly what failed and why in plain language, providing a flat-rate price before any work begins. You approve the repair, we perform it, and we run the system through multiple cycles to ensure it's fixed.
Repair vs. Replacement
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. We repair furnaces of all ages, including 20+ year old units. However, when parts availability on very old units makes repair impractical or when the cost of frequent repairs outweighs the benefit of a new unit, we will tell you clearly.
We don't use high-pressure sales tactics. Our goal is to give you the information you need to make a decision that makes sense for your budget and your home's long-term comfort.
Cost and Value
We believe in transparency. Our diagnostic fee is $125–$175, which includes a full CO safety check. Common repairs like ignitor or flame sensor replacements typically range from $100–$300, while more involved repairs like gas valves or control boards range from $300–$600.
We don't hide costs. You'll know the price before we touch the equipment. We focus on providing value through accurate, lasting repairs that prevent the need for costly callbacks.
Safety First
Your family's safety is our priority. A furnace that isn't venting properly or has a cracked heat exchanger can be a serious health risk. That is why every single service call includes a CO combustion analysis.
If we find a safety issue, we will explain it clearly and show you the evidence. We never use safety concerns as a scare tactic to sell new equipment. We provide the facts so you can make the right decision for your home.
Scheduling Your Service
We are based on Fairfax Avenue and serve the entire Larchmont area. We understand that when your furnace is down, you need help quickly. We stock common parts like ignitors, flame sensors, and pressure switches on our trucks to facilitate same-day repairs whenever possible.
Call us at (323) 970-3113 to schedule. We will confirm a time that works for you and arrive ready to diagnose and resolve the issue.
Common Furnace Mistakes
One of the most common mistakes we see is homeowners ignoring minor noises or smells until the system fails completely. A grinding noise often indicates a failing blower motor bearing, which can lead to a much more expensive repair if ignored.
Another mistake is neglecting the flame sensor. A dirty sensor is a simple, inexpensive fix, but if left alone, it can cause the furnace to shut down repeatedly, putting unnecessary stress on other components. Regular maintenance and prompt attention to small issues save you money in the long run.
Is Your Furnace Worth Repairing?
Deciding whether to repair or replace depends on the age of the unit, the cost of the repair, and the overall condition of the system. If your furnace is over 15–20 years old and requires a major repair like a heat exchanger or a control board, it is worth considering the long-term cost-benefit of a new, more efficient system.
However, if it's a simple fix like an ignitor or a sensor, a repair is almost always the right choice. We will give you the honest, plain-spoken advice you need to decide what is best for your home. We don't push for replacement unless it is truly the most logical path forward.

What Larchmont customers say about gas furnace repair
Verified reviews from homeowners in Larchmont and nearby neighborhoods who used our gas furnace repair service.
“Full system replacement in our 1930s Hancock Park home — not easy given the older construction. LC handled all the challenges: narrow access, old ductwork, low attic. Finished on time and on budget.”
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
